A Simpler Web App Architecture (jDays 2016)
4 likes2,215 views
The document discusses the advantages and techniques of combining server-side and client-side web architecture, emphasizing independent deploys, partial updates, and improved caching. It presents examples like pjax for HTML updates and client-side includes for reusable content. Acknowledging the challenges of device diversity and time-to-first-render, it advocates for richer interactions and better compatibility through custom elements and shared widgets.
A Simpler Web App Architecture (jDays 2016)
- 1. A Simpler Web Architecture. Gustaf Nilsson Kotte @gustaf_nk
- 2. “server-side vs client-side” static web pages vs dynamic web app? no! either/or → both/and
- 3. Elevator pitch Demonstrate client-side techniques that makes server-side rendering a feasible choice for your web applications.
- 4. General sanity checks Does the tool add value? What are the requirements?
- 5. what is your foundation?
- 6. client-side web benefits independent deploys partial updates caching cross-team widgets enables rich interactions
- 7. client-side web challenges technological progress → device diversity time-to-first-render (✓ isomorphic javascript) “EnhanceConf - Forbes Lindesay - Server Side Rendering”, https://m.youtube.com/watch?v=CBnd3EzIZCo interoperability/evolvability rate of change
- 8. techniques
- 9. techniques web server enables server-side web (architectural foundation) pjax → partial updates (HTML views over ajax) client-side includes (caching and reusable content) server-side driven client refreshes custom elements → shared widgets
- 10. web server
- 11. “a web server that uses an API” a.k.a... gateway web server web frontend server HTML serving API gateway web backend for frontend (BFF)
- 13. server-side web ✓ independent deploys (gateway web server)
- 14. pjax
- 15. pjax jquery-pjax (GitHub 2011) https://github.com/defunkt/jquery-pjax pushState ajax ~500 LOC (not counting comments) jQuery dependency
- 16. jquery-pjax
- 17. jquery-pjax multiple containers (be careful) don’t overlap event handlers rewrite in progress (very exciting) https://github.com/defunkt/jquery-pjax/issues/498
- 19. server-side web ✓ independent deploys (gateway web server) ✓ partials updates (pjax)
- 21. client-side includes hinclude.js https://github.com/mnot/hinclude/ 2005 by Mark Nottingham (@mnot) https://en.wikipedia.org/wiki/Mark_Nottingham ~150 LOC (not counting comments)
- 22. hinclude.js
- 23. h-include.js custom element version of hinclude.js https://github.com/mnot/hinclude/pull/46 custom element polyfill: 3KB https://github.com/WebReflection/document-register-element includes in includes, etc etc
- 24. server-side driven client-side refreshes shared list of known domain events server: client:
- 25. demo
- 26. server-side web ✓ independent deploys (gateway web server) ✓ partials updates (pjax + client-side includes) ✓ better caching (client-side includes)
- 27. widgets
- 28. widgets internal/external dependencies? either need to agree (now and later) or bring their own (page weight) what to do?
- 29. → widgets separate content from execution code repository for custom elements no dependencies custom element enhances content think about compatibility
- 30. demo
- 31. server-side web ✓ independent deploys (gateway web server) ✓ partials updates (pjax + client-side includes) ✓ better caching (client-side includes) ✓ cross-team widgets (client-side includes + custom elements)
- 32. summary
- 33. techniques web server enables server-side web (architectural foundation) pjax → partial updates (HTML views over ajax) client-side includes (caching and reusable content) server-side driven client refreshes custom elements → shared widgets (free from dependencies)
- 34. example scenario: static e-commerce site
- 35. example scenario: dynamic web app
- 36. client-side web benefits independent deploys partials updates better caching cross-team widgets enables rich interactions
- 37. server-side web ✓ independent deploys (gateway web server) ✓ partials updates (pjax + client-side includes) ✓ better caching (client-side includes) ✓ cross-team widgets (client-side includes + custom elements) ~ enables rich interactions (do you really need it?)
- 38. General sanity checks Does the tool add value? What are the requirements?
- 39. why is server-side web simpler? (technological progress → device diversity) less moving parts working with the browser better evolvability lower rate of change
